地下厂房岩锚吊车梁结构稳定计算的研究现状

Current situation research on calculation of structural stability for the rock-bolted crane girder in the underground house

岩锚吊车梁作为一种新兴的先进结构形式,近年来在水电站地下厂房中得到了普遍的应用。岩锚吊车梁结构稳定计算所普遍采用的方法有刚体平衡法和有限单元法。通过对两种方法的介绍,分析其中所存在的缺陷和问题,对岩锚吊车梁结构稳定计算的研究现状进行了总结,并对发展的前景进行了展望。

Rock-bolted crane girder has been widely applied in the underground house of hydropower plant as a new structural form recently. The methods of calculation for the structural stability of rock-bolted crane girder include the rigid equilibrium method and the finite element method. By introducing two methods and analyzing the problems and defects of the methods, summarize the current situation of development for the calculation of structural stability for rock --bolted crane girder, and forecast the situation of development in the future.
